||What exactly happens to the Deckers, hackers who plug their brains directly into computers and control the mainframe with the mere firing of excitatory synapses? The neurotransmitter at excitatory synapses depolarizes the postsynaptic membrane of a neuron. Example: acetylcholine (ACh) Binding of acetylcholine to its receptors on the postsynaptic cell opens up ligand-gated sodium channels. These allow an influx of Na+ ions, reducing the membrane potential. This reduced membrane potential is called an excitatory postsynaptic potential or EPSP. If depolarization of the postsynaptic membrane reaches threshold, an action potential is generated in the postsynaptic cell. But anyway, what happens to a Decker who goes offline, and is lost in the electronic flow of the Internet? One can never know for sure...|
